Nice going, Spider-Man.

The first official trailer for the upcoming Marvel’s ultimate team-up movie to end all other team-up movies, Avengers: Infinity War, has dropped online due to Tom Holland.

Holland, who plays Peter Parker — aka Spider-Man — in Spider-Man: Homecoming, was opening a package during an Instagram Live stream, sent to him by co-star Mark Ruffalo. Inside the package was the first Infinity War, to which he proudly displayed to the camera.

“Hi Tom,” the note read. “I’m so excited to be working with you on Infinity War. I thought you’d like to be the first to see the poster for the movie. Enjoy, Mark Ruffalo.”

Upon turning it over, he found “CONFIDENTIAL. DO NOT SHARE,” written in bold font. Holland freaked out and quickly turned off the camera, but the damage had already been done.

Both Holland and Ruffalo have been reprimanded by Marvel in the past for accidentally sharing secrets. While the video is certainly staged, it’s a fun and humorous way to build the hype for the movie.

And now we have our first look at the Infinity War poster. It looks similar to the previous first posters for Avengers and Avengers: Age of Ultron — that being a giant letter A and no actual characters — but it’s an effective tease.

Even better news is that Marvel has announced the first Infinity War trailer will be arriving on Wednesday, Nov. 29. They even released a nostalgic teaser video of everything leading up to Infinity War to get people even more excited.
